Correct Answer: C

Rationale: Pulling to a standing position typically occurs between 11 to 12 months, marking the progression towards walking.

Correct Answer: D

Rationale: Neuroblastoma is a cancer that commonly originates in the adrenal glands located in the abdomen. It can also occur in nerve tissues along the spine, but it is most frequently found in the abdominal region. Therefore, the correct answer is D. Choices A, B, and C are incorrect as Neuroblastoma typically arises from neural crest cells in the adrenal glands or sympathetic ganglia, not in the bones, kidneys, or cortex.

Correct Answer: B

Rationale: The correct answer is B: Regression. Regression is a common defense mechanism where a child reverts to an earlier stage of development, such as thumb-sucking, to cope with stress. In this scenario, the 6-year-old boy is using thumb-sucking (a behavior typical of earlier developmental stages) as a way to deal with the stress of surgery. Repression (choice A) involves unconsciously blocking out thoughts or feelings, which is not applicable in this case. Rationalization (choice C) is a defense mechanism where illogical or unreasonable explanations are provided to justify behavior, which is not relevant here. Fantasy (choice D) refers to the use of imagination to escape from reality, which is also not the appropriate defense mechanism for the situation described.
